Description

Technical Field

[0001] This invention relates to the field of bathroom product technology, and more specifically, to a shower structure that leaves no residual water. Background Technology

[0002] Most existing shower devices employ a residual water drainage mechanism similar to the one disclosed in Chinese patent CN212928866U. This mechanism involves a water pipe between the shower column and the faucet, with a drain outlet and a pull rod on the side wall of the pipe. Operating the pull rod causes a plug to either seal or open the drain outlet. When the plug seals the drain outlet, water flows into the shower column to supply water to the overhead shower. When the drain outlet is open and the faucet is closed, the water remaining in the shower column is drained. However, in this type of solution, the drain outlet only drains residual water from the shower column. Residual water in the overhead shower needs to be drained through the showerhead's nozzle. Therefore, even after the water is turned off, the overhead shower may continue to drip for a period of time due to residual water, or drip cold water during the next use, resulting in a poor showering experience. Furthermore, if the user forgets to operate the pull rod after showering, the residual water will not drain automatically, which is inconvenient for the user. Summary of the Invention

[0003] This invention discloses a shower structure that eliminates residual water, aiming to improve the problems of existing shower devices that do not automatically drain residual water from the shower column after the water is turned off and cannot simultaneously drain residual water from the overhead shower.

[0004] The present invention adopts the following solution: A water-residue-free shower structure includes a shower rod and a water-residue drainage assembly installed at the bottom of the shower rod. The water-residue drainage assembly includes a water-passing body and a diaphragm. The water-passing body has an inlet channel for connecting to a faucet, an outlet channel for connecting to the water outlet of the shower rod, and a drain channel for connecting to a drain outlet. When the water flow is turned on, the diaphragm abuts against the inlet end of the outlet channel under the pressure of the water flow. At this time, the outlet channel is separated from the drain channel and is connected to the inlet channel through the inlet on the diaphragm. When the water flow is turned off, the diaphragm returns to its original position, and the inlet is sealed by a sealing part. At this time, the outlet channel is separated from the inlet channel and is connected to the drain channel to form a siphon effect, drawing residual water in the overhead shower into the drain channel.

[0005] As a further improvement, the inlet cross-sectional area is smaller than the outlet cross-sectional area, and the outlet cross-sectional area is not smaller than the outlet cross-sectional area.

[0006] As a further improvement, the diaphragm is disposed at the outlet end of the water inlet channel, its periphery is fixed to the water-passing body, its center protrudes upward, and a retractable folding part is provided along the periphery of the protrusion, and the water inlet is provided through the center of the protrusion.

[0007] As a further improvement, the water outlet end of the water inlet channel is provided with multiple water outlet holes along the circumferential direction, and a hemispherical sealing part is protruding in the middle of the water inlet channel. The diaphragm is disposed above the sealing part, and the water inlet is directly facing the sealing part.

[0008] As a further improvement, the water-passing body includes a water-passing base, a water-exit cover, and a connecting base. The water-passing base is formed with the water inlet channel and the water outlet section of the water outlet channel. The water outlet section is arranged parallel to the water inlet channel. The water outlet cover is formed with the water outlet channel, a guide hole, and a first connecting part. The connecting base is provided with a second connecting part. The first connecting part and the second connecting part cooperate to form the water inlet section of the water outlet channel. The guide hole is located at the water inlet end of the water inlet section.

[0009] As a further improvement, one side of the water outlet cover is provided with a pressing part for pressing the diaphragm, and the other side is provided with a plurality of guide holes along the circumference of the water outlet channel.

[0010] As a further improvement, the water outlet cover is disposed on the top of the water inlet seat, the connecting seat is fixedly connected to the water outlet cover, and is provided with a shaft portion for connecting with the plug connector. The shaft portion is provided with a slot and is engaged and limited by a retaining ring with a retaining groove on the plug connector.

[0011] As a further improvement, the top spray is provided with a water storage tank, which is located at the lowest position of the water outlet surface inside the top spray, and the outlet end of the water inlet pipe connected to the water outlet path extends into the water storage tank.

[0012] As a further improvement, the inner water outlet surface is configured to slope upwards around the water storage tank, the top spray is oscillatingly connected to the water inlet pipe, and the oscillation angle of the top spray is less than the angle between the inner water outlet surface and the center line of the water storage tank.

[0013] As a further improvement, the top sprayer is provided with multiple water outlets, and the water inlet end of each water outlet is provided with a step that protrudes upward from the inner water outlet surface.

[0014] By adopting the above technical solution, the present invention can achieve the following technical effects: 1. When the water is turned on, the inlet and outlet channels on the diaphragm are connected, allowing water to flow from the faucet into the inlet channel and then into the outlet channel, flowing along the shower rod's water path to the overhead shower. When the water is turned off, the inlet on the diaphragm abuts against the sealing part, blocking the inlet. Since the residual water drainage component is located at the bottom of the shower rod, a siphon effect is created under the pressure of the water flow and atmospheric pressure, allowing residual water in the outlet channel and the overhead shower to be drawn into the drainage channel and then flow out from the drain outlet. This means the user only needs to turn off the water to automatically drain residual water, preventing the user from forgetting to do so and improving usability. Simultaneously, the residual water in the overhead shower is also drawn into the drainage channel, preventing continuous dripping and enhancing the user experience, allowing for instant shut-off of the overhead shower.

[0015] 2. The inlet cross-sectional area is smaller than that of the outlet channel to ensure that the diaphragm can move away from the sealing part under the water pressure and abut against the inlet end of the outlet channel to isolate the outlet channel from the drain channel; the inlet cross-sectional area of ​​the drain channel is not smaller than that of the outlet channel to ensure the formation of the siphon effect, so that the residual water in the shower rod and the overhead shower can be automatically discharged.

[0016] 3. A water storage tank is provided at the lowest point of the water outlet surface inside the top sprayer, and the outlet end of the water inlet pipe connected to the water outlet extends into the water storage tank. When the water is turned off, the water flow can be gathered at the lowest point, and the water in the water storage tank is drawn into the water outlet through the water inlet pipe, so that it flows from the water outlet to the drainage channel.

[0017] 4. The inner water outlet surface is designed to slope upwards around the water storage tank, preferably in a funnel shape, which is more conducive to the collection of residual water in the water storage tank, so as to realize the immediate shut-off of the top spray. The top spray and the water inlet pipe can be swung, and the swaying angle of the top spray is less than the angle between the inner water outlet surface and the center line of the water storage tank, so as to ensure that the residual water of the top spray can flow into the water storage tank.

[0018] 5. Each water outlet has a step that bulges upward from the inside of the outlet to prevent water from dripping after the water is turned off. The minimum diameter of the water outlet is set to no more than 0.8mm. The small diameter further ensures that the water flows to the water storage tank first and does not flow out of the outlet, achieving the effect of stopping the water flow immediately after turning it off.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The terms “first,” “second,” etc., are only used to distinguish different objects and should not be construed as indicating or implying relative importance or the quantity, specific order, or primary or secondary relationship of the indicated technical features. The term “several” means one or more, and “multiple” means two or more, unless otherwise explicitly specified. Example

[0024] Combination Figures 1 to 12 This embodiment provides a shower structure with no residual water, including a shower rod 1 and a residual water drainage assembly installed at the bottom of the shower rod 1. The residual water drainage assembly includes a water-passing body 2 and a diaphragm 3. The water-passing body 2 has an inlet channel 21 for communicating with a faucet 5, an outlet channel 22 for communicating with the water outlet 11 of the shower rod 1, and a drain channel 23 for communicating with a drain outlet 51. When the water flow is turned on, the diaphragm 3 abuts against the inlet end of the outlet channel 22 under the action of water flow pressure. At this time, the outlet channel 22 is separated from the drain channel 23 and is connected to the inlet channel 21 through the inlet 31 on the diaphragm 3. When the water flow is turned off, the diaphragm 3 is reset, and the inlet 31 is blocked by the sealing part 24. At this time, the outlet channel 22 is separated from the inlet channel 21 and is connected to the drain channel 23 to form a siphon phenomenon to draw the residual water in the top spray 4 into the drain channel 23. Preferably, the drain outlet 51 is provided on the faucet 5. It can be a separate water outlet or it can be shared with the water outlet at the bottom. It is not limited to this and is not specifically limited.

[0025] It should be noted that in this embodiment, when the water is turned on, the inlet 31 on the diaphragm 3 is connected to the outlet channel 22. At this time, the water flows from the faucet to the inlet channel 21, and then enters the outlet channel 22 to flow along the water outlet path 11 of the shower rod 1 to the top spray 4. When the water is turned off, the inlet 31 on the diaphragm 3 abuts against the sealing part 24. At this time, the inlet 31 is blocked by the sealing part 24. Since the residual water drainage component is located at the bottom of the shower rod 1, a siphon effect is formed under the action of water pressure and atmospheric pressure, so that the residual water in the outlet path 11 and the residual water in the top spray 4 can be sucked into the drainage channel 23 together, and then flow out from the drain outlet 51. In this way, the user only needs to turn off the water to achieve automatic drainage of residual water after turning off the water, so that the user will not forget to drain the residual water, which is beneficial to the user. At the same time, the residual water in the top spray 4 can be sucked into the drainage channel 23, which can avoid the problem of continuous dripping caused by the residual water in the top spray 4, improve the user experience, and realize the ability to turn the top spray 4 off and on immediately.

[0026] In a preferred embodiment, the inlet cross-sectional area of ​​the water inlet 31 is smaller than that of the outlet cross-sectional area of ​​the water outlet channel 22, so as to ensure that the diaphragm 3 can move away from the sealing part 24 under the action of water flow pressure and abut against the inlet end of the outlet channel 22 to isolate the outlet channel 22 from the drain channel 23; the inlet cross-sectional area of ​​the drain channel 23 is not smaller than that of the outlet channel 22 to ensure the formation of the siphon phenomenon, so that the residual water in the shower rod 1 and the top spray 4 can be automatically discharged. It is easy to understand that when the water flow is turned on, the inlet channel 21 and the outlet channel 22 are connected. At this time, the entire shower rod 1 and the top spray 4 are full of water flow. When the water flow is turned off, the inlet 31 is immediately blocked by the sealing part 24. At the same time, the inlet channel 21 of the drain channel 23 is connected, and its drain outlet 51 is located below the top spray 4. At this time, the shower rod 1 is equivalent to a U-shaped pipe filled with water in the siphon phenomenon. Therefore, the water flow in the top spray 4 at the high water level can be sucked into the drain channel 23 at the low water level.

[0027] Based on the above embodiments, in an optional embodiment of the present invention, the diaphragm 3 is disposed at the outlet end of the water inlet channel 21, its periphery is fixed to the water-passing body 2, its center protrudes upward 32, and a retractable folding part 33 is provided along the periphery of the protrusion 32, with the water inlet 31 passing through the center of the protrusion 32. When the water is turned on, under the action of the water flow below, the folding part 33 extends upward, so that the central protrusion 32 abuts against the water inlet end of the outlet channel 22, at which time the water inlet 31 is away from the sealing part 24. When the water is turned off, under the action of the water flow above, the folding part 33 retracts downward, so that the central protrusion 32 abuts against the sealing part 24, thereby sealing the water inlet 31. The folding part 33 provides sufficient elasticity for the diaphragm 3, which can ensure the sealing performance of the diaphragm 3. The diaphragm 3 is integrally molded, preferably made of rubber or silicone, but not limited to these, and is not specifically limited.

[0028] In another embodiment, the water outlet end of the water inlet channel 21 is provided with a plurality of water outlet holes 211 along the circumferential direction, and a hemispherical sealing part 24 protrudes from the middle of the water inlet channel 21. The diaphragm 3 is disposed above the sealing part 24, with the water inlet 31 facing the sealing part 24. In the water-off state, the periphery of the water inlet 31 of the diaphragm 3 abuts against the sealing part 24. The hemispherical arrangement of the sealing part 24 can reduce the resistance during the movement of the middle part of the diaphragm 3 and avoid the problem of the diaphragm 3 being torn or worn, which is beneficial to ensuring the service life of the diaphragm 3. By setting the sealing part 24 and the water outlet holes 211 together at the water outlet end of the water inlet channel 21, the number of parts can be reduced, making the structure more compact.

[0029] In one embodiment, the water-passing body 2 includes a water-passing base 25, a water-exit cover 26, and a connecting base 27. The water-passing base 25 has an outlet section 231 formed with an inlet channel 21 and a drain channel 23. The outlet section 231 is arranged parallel to the inlet channel 21. The water-exit cover 26 has an outlet channel 22, a guide hole 261, and a first connecting portion 262. The connecting base 27 has a second connecting portion 271. The first connecting portion 262 and the second connecting portion 271 cooperate to form the inlet section 232 of the drain channel 23. The guide hole 261 is located at the inlet end of the inlet section 232. For example, the inlet section 232 and the outlet section 231 of the drain channel 23 are perpendicular in orientation, which facilitates the arrangement of the channels and makes full use of the structural space. When the water flow is turned off, the residual water flows from the outlet channel 22 to the guide hole 261, then enters the inlet section 232 of the drainage channel 23, and then flows from the outlet section 231 of the drainage channel 23 to the drain outlet 51.

[0030] Furthermore, one side of the water outlet cover 26 is provided with a pressing part 263 for pressing the diaphragm 3, and the other side is provided with a plurality of guide holes 261 along the circumference of the water outlet channel 22. The pressing part 263 is annular and protrudes along the water outlet cover 26 to press the periphery of the diaphragm 3. The guide holes 261 are arranged along the circumference of the water outlet channel 22 to shorten the flow path and facilitate mold opening. It should be noted that the total cross-sectional area of ​​the water inlet of each guide hole 261 is not less than the cross-sectional area of ​​the water inlet of the water outlet channel 22.

[0031] In other embodiments, the water outlet cover 26 is disposed on the top of the water outlet seat 25, and the connecting seat 27 is fixedly connected to the water outlet cover 26 and is provided with a shaft portion 272 for connecting to the plug connector. The shaft portion 272 has a slot 2721 and is locked in place by a retaining ring 14 engaging with a slot on the plug connector 12. The plug connector 12 is connected to the inner tube 13 of the shower rod 1. During installation, the connecting seat 27 is inserted into the plug connector 12, and then locked in place by the retaining ring 14. The insertion method allows for quick assembly and disassembly. This is not a limitation and is not specifically restricted.

[0032] Based on the above embodiments, in an optional embodiment of the present invention, the top spray 4 is provided with a water storage tank 41, which is located at the lowest position of the water outlet surface 42 inside the top spray 4. The outlet end of the water inlet pipe 43, which is connected to the water outlet channel 11, extends into the water storage tank 41. When the water is turned off, the water flow can converge at the lowest position and be drawn into the water outlet channel 11 through the water inlet pipe 43, so that the water flows from the water outlet channel 11 to the drainage channel 23.

[0033] In one embodiment, the inner water outlet surface 42 is designed to slope upwards around the water storage tank 41, preferably in a funnel shape. This facilitates the collection of residual water within the water storage tank 41, enabling immediate shut-off. It is easy to understand that after the water is turned off, the water remaining in the top spray 4 will flow along the inner water outlet surface 42 into the water storage tank 41. The top spray 4 is oscillatingly connected to the inlet pipe 43, and the oscillation angle of the top spray 4 is less than the angle between the inner water outlet surface 42 and the centerline of the water storage tank 41. For example, a ball head 431 is provided on the inlet pipe 43, allowing the top spray 4 to oscillate around the ball head 431 to adjust the water outlet angle. Since its oscillation angle is less than the angle between the inner water outlet surface 42 and the centerline of the water storage tank 41, it ensures that residual water flows into the water storage tank 41.

[0034] Furthermore, the top spray 4 is equipped with multiple water outlets 44, and each water outlet 44 has a step 441 protruding upward from the inner water outlet surface 42 at its inlet end. This prevents water from dripping from the water outlet 44 after the water is turned off, ensuring that residual water can collect along the inner water outlet surface 42 into the water storage tank 41 instead of flowing out from the water outlet 44, thus achieving the effect of immediate shutdown when the top spray 4 is turned off. In other embodiments, the minimum diameter of the water outlet 44 is set to no more than 0.8 mm. The small outlet diameter of the water outlet 44 further ensures that the water flow preferentially flows to the water storage tank 41, achieving the effect of immediate shutdown when the water is turned off.

[0035] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions that fall within the scope of the present invention are within the scope of protection of the present invention.
